drop_database
DROP DATABASE(7) PostgreSQL 9.2.7 Documentation DROP DATABASE(7)NAME
DROP_DATABASE - remove a database
SYNOPSIS
DROP DATABASE [ IF EXISTS ] name
DESCRIPTION
DROP DATABASE drops a database. It removes the catalog entries for the database and deletes the directory containing the data. It can only
be executed by the database owner. Also, it cannot be executed while you or anyone else are connected to the target database. (Connect to
postgres or any other database to issue this command.)
DROP DATABASE cannot be undone. Use it with care!
PARAMETERS
IF EXISTS
Do not throw an error if the database does not exist. A notice is issued in this case.
name
The name of the database to remove.
NOTES
DROP DATABASE cannot be executed inside a transaction block.
This command cannot be executed while connected to the target database. Thus, it might be more convenient to use the program dropdb(1)
instead, which is a wrapper around this command.
COMPATIBILITY
There is no DROP DATABASE statement in the SQL standard.
